I wrote a similar system for PalmOS based hand held devices. The plan was to use them, one per table, as a poor man's BridgeMate. At the end of the evening the data would be beamed (the models we purchased on Ebay were the low end ones, no wifi, just infra-red) to a laptop and the evening's sessions scored automatically. Several members refused to use them, so we stopped using them at the club. However I use mine all the time, rather than using a score sheet and pen. It knows all the movements of all the local clubs I play at and is very useful for scoring Chicago sessions when I play social bridge. I recently added team scoring support, it will work out your team's IMP points, but I've not used this yet, so remains untested. Several people have expressed interest in the software, but don't have the required hardware, so I think there would be interest in a Smartphone based application. The Palm binary and movement files are available as a zip file on our club's website along with a zip file of the program source code, http://bridgewebs.com/kippington, scoring software menu.
