Might need something a bit more powerful than a little linksys m8, depending on range. Another important consideration is that external antennae are against EU directives over here and thus to use one you need express council permission (obtained at planning offices) else risk some hefty fine-age.
In principle tho look for commercial routers to do the job, not cheap tho.
You sure on that?
We do this type of work every week - some of this is for the council. We also have a wireless hotspot at a camp site, we needed no planning permission. We use the Cisco Omni-Directional antennae on most sites, they have a pretty large range! Email me at my address in my trust and I can give you further info on hardware and software to use.

Edit #2: Ultra_Extreme, you do realise that BT Openzone use Netgear routers/access points? They are just re-boxed to make them look like BT's own, the board etc is all Netgear and not the ProSafe stuff - just the normal home-going stuff
