Cost effective way to introduce OWA?

[Bleek]

What would be the best method of installing Outlook Web Access from a home office, obviously using a static IP (Business Broadband).

Win 2008 with built-in ISA firewall (software) on a cheap tower server?

I've never installed OWA before so is there anything I should look out for, requirements and caveats?

You need to do lots of config work on the OWA box - MS website for docs.

Would Logmein or similar not work ?

Well I only really know Exchange but if you have other suggestions that are simpler and just as usable (familiar front end etc) then please let me know.

5 users is currently about the size required, all remote workers.

I'll take a look at the hosted option, might just take the simple route!
