Demo version is full featured FlowTuner, but it contains limitation
of maximum session length: demo doesn't handle sessions longer than 10
minutes.
In order to work FlowTuner requires Java
Runtime Environment (JRE). If you already have JRE, to save download
time download version without integrated JRE. If not or unsure download
demo version with integrated JRE.
For your convenience this software contains sources of
poptop and pppd software
distributed under terms of GPL license. If you wish you can
download it separately from their web sites.
