An old post, but chipping in here; Tom and I are full time on Light Blue Software, www.lightbluesoftware.com , built in RealStudio (not Xojo yet - we need 10.6 compatibility for now); I'm in Cambridge, and he's in Crouch End in London.
We are from Wimbledon and wor full time writing art gallery management software and collection system . We used Xojo 2013r3 .3 for compiling to OSX 10.6 and Xojo 2013r4.1 to generate carbon application.
I've been back in the UK living in Somerset for a little over a year now. Had spent the previous couple of years in New Zealand, and before that was in Scotland for about 17 years. Born and bred in East Sussex though!
