Hello there,
I am an authorized dealer of both the ikeGPS and ESRI software. ikeGPS offers and ikeExension for ArcPad. For customized forms a pre-existing ikePoint.shp is modified via ArcStudio. In this case all hardware features of the ikeGPS can be utilized. An ArcPad license is required. You are limited to shapefile format. I have assisted in such developments many times. You may wish to investigate ikeTools software. I am happy to answer further questions.
Sincerely,
Adam Tyler
