My Treo 300 just arrived!!!!!

I have a home network with an SMC barricade. I was thinking that if our Sprint internet service is "always on", we might have a static IP. If that is the case, I can access my home system from my Treo. This would be good if I want to get a file to email or acceess photos or music from my home system.

Does anyone have any more information on this??
