Thanks a lot for your reply thomas :) That's helped clear up quite a few things.
I've managed to now get the basic initial interface screen working now
and its looking good :) I'm hoping to open source this once I've
finished but with it being uni I'm not holding my breath :/

I am currently using the use elements, only problem was that the
button was different sizes depending on the text. Thank god I found
the text-anchor ;)
My question was actually about using Element.appendChild to the
Document, but I noticed when I was debugging that batik uses its own
classes to construct the document in the background anyway, so I guess
I don't need to worry about that :)

I had a feeling it was the filter, and as soon as I took it away it
worked :) bit of a shame, it looked really good, I may implement that
as a setting that can be toggled by the user for fast machines (my one
at home is a mid to low-range machine).

I looked at the examples and liked them :) only problem with them is
that they don't really give you any java-related examples. i guess
that's why I downloaded the squiggle source :)

I'm not sure to be honest, it was suggested to me and I thought it was
a good idea at the tme. The card would be 500bytes max so no issues
with bandwidth, and in my server-client model it makes sense, since
the client is very "dumb" and all of the processing is done on the
server. I also didn't want to take up a huge amount of memory with
loading the cards in (ok, it is only 35K total, but we know what java
is like ;)).

That's how I have it atm, I'm gonna use those if I don't have enough time :)

Changed :) had a feeling there was an easier way.
Again, thanks for your help :)
