Headworx has found a way around this, and copied the Pocket PC .exe file across to his Smartphone. After using SOTI Pocket Controller - the excellent program for remotely controlling your Smartphone / Pocket PC - he managed to get it logged in. The only problem appears to be the power under the hood of the SP5m, which isn't quite enough for a good quality Skype call, however it does show that Skype VoIP calls should be possible on a Smartphone if enough bandwidth and CPU size is available.
