Hey guys, my dad is moving his small business from his corporate office to his home, He has asked me to setup everything

Whats going to be connected:
2 x Desktop with XP Pro SP3 (Nod32)
2 wrie modem
Kyocera Network printer (scaned files, ifax etc.)
Phone system


What I am thinking:
Connect 2 wire modem (has inbuilt firewall, wireless, content filtering etc.)
Connect two PCs to the network,

This is where im abit stuck, I have two options
1. Build WHS out of an old P4 box and save to network drives, from here use online backup to provide additional security, either jungle disk or mozy) My main reason for this is in the event of a HDD failure I could rebuild a new HDD with minimal down time.

2. Save all data locally to each PC and then back up to an external HDD (something like active sync), this external HDD will be keeped off site.




Additional requirements:
There is an additional employee that will work on the road, I read that one of the WHS add ins has the ability to back up to the WHS whether it was connected locally or via the internet. Can anyone tell me the name of this add in :)

When the employee comes to my dads home any new / modified files need to be uploaded to the WHS as well as take a smapshot of the image. will WHS automatically backup a laptop connected wirelessly once it has been detected on the network?

A cheap free way of controlling / mangaing PCs remotley. For this I will need to get my ISP to provide me with a static IP


Please let me know what you think

Cheers
