OK I tried Splashtop. Wow! I really don't know how it does what it does. Flash is nothing with it.... works like a charm.
At first I was ticked that it was only 1024 x 768 resolution but being the same as the iPad it was really not bad at all. The main thing is how it manages to send out video and sound like it does.... and in sync. My main remote control app can do sound, but NO WAY can it do video like that... not even close.
And of course Flash is a piece of cake with Splashtop.
My PC is on 24/7 anyway so no issue with that. And I'm already used to forwarding ports for RDP, VNC, etc.... so getting it to work over 3G was a cinch. No searching for port numbers.
