My advice is to throw money at the problem. Get a refurbished low-end MacBook from Apple for less than $1000 and have your OmniFocus setup go with you to the office. Or for even less money, but an unknown wait, get an iPad and OmniFocus for iPad (due out real soon). You can run your existing copy of OmniFocus if you go the laptop route, no need to buy another.

There's been some talk of Omni building some sort of OmniFocus net application that you could interact with from your web browser, but I haven't heard anything that suggests you'll be able to make use of such a thing this year.
