VPN for LogMeIn
Essentially, I was using my work computer through a secure, encrypted connection, but without any of the obnoxious failures and hassles that come with running a VPN that affects my entire system. One big plus was having access to my local email archives, as well as those still living on Microsoft Exchange server. The problems I've encountered have been minor. There's the lag, and the fact that file transfers are only available for users who upgrade. The only other drawback to LogMeIn is if the host computer suffers a fatal crash and won't restart. Unless a friend will go push the power button, you won't be able to get in and you'll have to resort to a VPN connection, which won't give you access to files on a local drive.
Throw in that big bagel of a price, and LogMeIn Free has become my first option for work-specific remote access.
