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.
