I just purchased my N800. I'm still a total noob on this thing, however I'm going to figure it out right away. As for your PPTP connection - if you can find the PPTP-client sources and compile it you should be fine, I don't know yet how compatible the arm binaries from debian are - but they will work, the only thing you need to worry about is the MPPE compression from M$ that needs to be built into the kernel, possibly as well patched into PPP. Once I can figure out how to rearrange this virtual keyboard so I can type IPs properly as well as use the PIPE | symbol I think I'll get myself testing the pptp-linux client.
