--- Comment #2 from Viktor Sarge <viktor.sarge at regionhalland.se> ---
Thanks for the input. I've read up on 10240 and while it is a good patch I feel
that the two are a bit apart even if 10240 might be a useful start to work with
the functionality described here. 

I guess it would go something like this: 

When issuing
* circulation.pl lights up a static page. 
* scan a barcode. 
* barcode is stored in a cache (javascript or indexedDB)
* barcode is lit up in the "barcode queue"-box.

These steps can take place as many times as you like at the same time as the
ones below. 

* the barcode that first arrived in the cache is sent to the server for
processing. 
* when a response arrives form the server the corresponding barcode is removed
from the cache and the visible "barcode queue"-box. 
* the correct response is displayed on circulation.pl. Multiple boxes requiring
to be handled could be displayed. 

Before going much further with this it might be a good idea to just have a go
with Plack and se if it makes the system more responsive. Not least since I
have a bit of a hard time convincing people on IRC that "scan as fast as you
like" is a good idea :)
