Fix'd. No idea about the thing though, I just ran Cat5e through my house. Far simpler.
This is for at work, and it's to connect a building which currently has a cable trailed out to it which gets upset whenever the wind blows which is a problem as it's in quite an open area
we've used these http://www.itreviews.co.uk/hardware/h1001.htm
ok,but slow.
no web interface. but no interface at all is there or needed.
advice above about being same ring mains applies
Use exterior grade Cat5e stuffs? Mega expensive but it's the proper solution.
Fibre optics isn't a bad idea either, however you'd need to protect it in a copper or plastic trunking at the very least.
Wireless bridge is also a good idea.
IP over mains is just asking for trouble. Especially in a commercial environment or area, who knows how many harmonics, inductive loads and transformers are going to be pissing on your packets. You might even find you're on a different phase of the supply in each building, causing further urination.
Have you checked with who ever looks after the power in the buildings? It's possible they'll either say there's no way it'll work, or have a total hissy fit at the suggestion of interfering in any way with their lovely electricity.
The guys at our place would likely have a similar reaction to what ours would be if someone asked if they could use our UPS to power their kettle, use the internal network to set up Windows file sharing, or utilise the disk space on the mail servers to store their files - it's not what was made for, and will potentially degrade the service in some way for other users.
for IP over mains to work they need to be on the same phase, been as it is going accross two buildings I very much doubt they would be on the same phase and if they are very large premises then they would be using 3 phase mains.
