Apparently you can convert coffee bags to tea but it can shorten the life of the cup (as they are designed for mugs). In addition the 15" bags do require the milk/tea ratio sensor to be electronically altered by a simple spoon shaped inductoresistive chip available on EBay.
Pah, you are all a bunch of heathens. Back in the good old days people used a long forgotten technique of using 'loose' tea leaves in a thing called (if I remember correctly) a Tea Pot. Now to stop the tea leaves getting into the cup a quant device called a strainer was used to pour the tea through.
I hope this helps.
Theres a local tea shop around here (Norwich) which sorts it all out for you, tea bags n'all. Very reasonable indeed. I'd avoid main dealers though and stick with the local.
Also I'm looking for a Lexus-style strainer as my current QD one is getting a little stained and lets face it, Lexus-style ones really are the future.
