Using from multiple computers

[CE]

I often have to work from different computers at work.
Textpad is installed on my 'main' computer, but if I call it from another pc on the network, I get the trial version of TP (with default settings, nagging messages, etc.)
Any way to call it from another node while using it's residing drive as 'boot', ie to run it remotely as if I was on the PC it is installed and licenced on ?

The work around would be to install it on all PC's, but I'd rather not right now.

Any help welcomed!
