I found some interesting comments with the ROC & ROP section in the 2008 NEC - I believe it answers you question to wheteher or not a keyless fixture can be mounted outside the footprint of the tub/shower & within the bathtub zone. I would question the difference in a track as opposed to an open bulb fixture. Last thought, a keyless is not a luminaire but I would interprete the keyless is subject to rule.
NEC 2005 Says no IMHO
D) Bathtub and Shower Areas No parts of cord-connected luminaires (fixtures), chain-, cable-, or cord-suspended-luminaires (fixtures), lighting track, pendants, or ceiling-suspended (paddle) fans shall be located within a zone measured 900 mm (3 ft) horizontally and 2.5 m (8 ft) vertically from the top of the bathtub rim or shower stall threshold. This zone is all encompassing and includes the zone directly over the tub or shower stall. Luminaires (lighting fixtures) located in this zone shall be listed for damp locations, or listed for wet locations where subject to shower spray.
2008 ROC --Recommendation: Revise text to read as follows: Change of language
(D) Bathtub and Shower Areas. No parts of cord connected luminaires, chain-, cable-, or cord-suspended luminaires, lighting track, pendants, or ceiling-suspended (paddle) fans shall be located within a zone measured 900 mm (3 ft) horizontally and 2.5 m (8 ft) vertically from the top of the bathtub rim or shower stall threshold. This zone is all encompassing and includes the space directly over the tub or shower stall. Luminaires located within the actual outside dimension of the bathtub or shower to a height of 2.5 m (8 ft) vertically from the top of the bathtub rim or shower threshold shall be marked for damp locations, or marked for wet locations where subject to shower spray.

Substantiation: This change helps to clearly identify the location and the requirements for lights in showers and bath tubs.
18-51 Log #1906 NEC-P18 Final Action: Accept States outside of the foot print is not considered a damp location/ still prohibits certain types of luminaires
(410.4(D))_______________________________________________________________
Submitter: James W. Carpenter, International Association of Electrical Inspectors
Recommendation: In the last sentence of 410.4(D), delete the phrase “in this zone” and replace it with the phrase “within the actual footprint of the bathtub rim or shower threshold” to read as follows:
“(D) Bathtub and Shower Areas. No parts of cord-connected luminaires (fixtures), chain-, cable-, or cord-suspended-luminaires (fixtures), lighting track, pendants, or ceiling-suspended (paddle) fans shall be located within a zone measured 900 mm (3 ft) horizontally and 2.5 m (8 ft) vertically from the top of the bathtub rim or shower stall threshold. This zone is all encompassing and includes the zone space directly over the tub or shower stall.
Luminaires (lighting fixtures) located in this zone within the actual outside dimension of the bathtub or shower to a height of 2.5 m (8 ft) vertically from the top of the bathtub rim or shower threshold shall be listed for damp or listed for wet locations where subject to shower spray.”
Substantiation: The word “zone” was changed in the last sentence of the first paragraph to make it consistent with the text used in 404.4 for switches and in the title for 406.8 for receptacles. The more appropriate word seems to be space since zone indicates the three-foot space outside of the footprint or space of the actual tub or shower. The text, as presently worded in the 2005 NEC, would imply that the area within three feet from the edge of the bathtub or shower is a wet or damp location requiring the luminaire to be listed for wet or damp locations. This would also logically carry over to any receptacle, switch, or luminaire that was located on the wall within this three ft distance, thus requiring the same wet or damp location rating for these devices or luminaires. Switches and receptacles would then be required to have a weatherproof cover installed. This three-foot area from the edge of the tub or shower is constructed of drywall with regular texture and paint. Any wetness or dampness in this area would cause rapid deterioration of the paint and drywall.
