well... let me see the code. Perhaps I'm just confused. I guess you may have done a good job anyway. Can you generate a patch and send it to me?

Ah, sorry then :-) But why were you avoiding it? I don't see the problem with this approach...
Plus, this way, we can have multiple devices connected to the server, which means that you can draw onto a simulator AND the real device simultaneously. (BTW, I also implemented the simulator ;-) )

Cestmir,
I'm afraid you did exactly what I was avoiding... I had on purpose the same code running both on the server and on the client.

I rewrote the architecture of the whole system to be client-server based. But I cannot commit my changes (see commandline dump below). Can someone help me?

Ive just tried revision 261. Few things:
laser-server.py line 53 delete ":" character
instead of rewriting LD call in each script, it would be great to
have config file like
LOCAL_DEVICE=true # or SRV_* for tcp SRV_HOST=localhost SRV_PORT=5000
and "library would" make connection directly to the device or via tcp based on that variables.
- code should automaticaly detect if the device is initializsed or not
(based on VendorID) and make that initialisation if its needed and draw. For example example1.py fails on comunicating with vendorID 3333 when device is directly connected and card is already initialised.
- security (optional)
- device probably shouldnt accept something like "draw a single dot for a long time". There is a chance somebody would stare to the lasaer instantly. - device shouldnt shine for a long time without intervention. It should stop drawing if nobody is sending "new things to draw", it shorten lifetime of the laser device otherwise. TIMEOUT=30min could be default for example.

I have commited new code without testing because I do not have access to the device. Please test svn revision 260 and report me any bugs introduced by this commit.
