On the seminar there has been spoken over a (future) Servoy-Mobile client, and all suggestions would be welcome.
I really think you should investigate the posibilities of: http://www.pocketpccreations.com/
It’s a real nice program where you can (quick) develop your own solutions, upload them to a pocketpc (local or by TCP/IP or GPRS etc..)
I am using this program for a while and it really works very nice. All data stored on the pocketpc is send by TCP/IP (in my case a GPRS-connection) to my local server and stored there in a local-database. Even a new solutionn (very tiny!) can be uploaded from the server to the PocketPC. Would be a killer-app if this is possible in Servoy!
Try it! Use it! And love it!
