bbk actually do a system that will work on phones and pda's with wifi capability, we use it at our 10th ic nationals, pretty good as over a half hour final you can get near live results on your handheld while pitting for your driver.
i beleive for it to work at worksop, then worksop need to have the "add on" to allow it to transmitt the data, which bbk have the rights too
