I got registered to the BOINC just yesterday. I'm wondeing if I can run the BOINC application on 2 PC's using the same account. One of the PC's would run at work and the other at home, so they will have 2 different IP addresses.
BOINC will run fine on multiple computers. Just use the same URL and authenticator to attach to all of them.
A quicker and easier way is to copy the account*.xml file(s) from a working computer to the new computer. This avoids any typo problems and also allows you to get set up even if the project(s) are down or running a different major version.
