Networking and Patch Panel questions....

dont use a hub - you will restrict bandwidth as they do not support full duplex communication - only one unit connected to it will be able to use the link at a time - If you use a switch it will share the connection between all shared devices.

The problem with wireless is - if you design your home network to run on wireless then great - but its a single point of failure. If your wireless router goes down - then you lose your network as you have no wired backup.
If you wire up the house like you originally planned - all rooms going into a patch panel - then you have a network that can cope with expansion in the future. so it can handle what you should be able to throw at it. Switches - Routers - Wireless access etc.

If I were renovating a house to sell - I would definately wire up the house to a patch panel - (as long as the patch panel was ina dry place - as someone stated above). If I was really going for it then I would use twin socket face plates in each room instead of single - just incase two laptops / or PC's wanted to use the network from the same place.
Whoever moved in would be able to run the network how they wanted with the wiring already in place.
