Thanks for all the very good information. I am trying to connect from home to a church. I do temperature control and would like to get into their computer remotely rather than having to drive 45 minutes to the site. The computers both run WinXP.
It's somewhat odd to see such enthusiasm for a DW product like the 7000! You don't see many positive comments about DW! I don't see an upgrade path from the 6000 (like they have for the 4000 to the 6000). And I don't think I'd get $30 more of value from a professional plan; unless I could get my employer to spring for the difference. But there's three chances of that...slim, fat, none.
Looks like VPN with my current setup is not much of an option.
What do you know about VNC?
