Okay i shall go for the low tech option

An isulated wire outsie is unlikely to be hit by lighting as i imagine you have points higher than this with exposed metal like the tv arieal

If you have a phone line going where you want you could be real brave an tape a new telephone wire and ethernet cable without plugs to it and try pulling it throught the house. The best way to do this is to get some string do a load of half hitches round it and tape it up and then attach new stuff to it. get one preson to feed and one to pull gently.

Dependant on the age of the house and how it has been wired you might be able to remove the sockets on the walls and run with the power cables but that would need loads of messing around.

Another thing is can you get under the floor to run cables under the house

If you have central heating see where the pipes go from downstairs to upstairs

Or if you are cohabiting with a woman convince her that you need to redecorate then once she has decided on a new colour scheme before you wall paper/paint cut a nice big channel through the plasterboard and run your cables. Also if it is a rented house some landlords can be persuaded to contribute to redecortion costs.
