Assume you mean TPA and yes many airport wireless access services selectively block certain sites.  Blackberry as a modem is very secure option as is a MiFi which I now use with an Ipad. (Good choice so I can read a book on plane)  Of course I'm a widower with no worries about someone checking up on me so your situation may be different.

But I use my broadband card and dont have an issue anywhere!

Remote to your home computer (if you are a geek like me and live it on and connected)....

A free, easy to use service is logmein.

Also nice to use from work
(Unfortunately I am more out and about than in my office these days...)
