The reason there are no free solutions is that (a) it's a lot of work,
and (b) if it's free then there is no return on the time invested!
Last time I looked, we estimated it would take a few months work and
would involve dealing with a number of different signature systems
from different vendors, many of whom charge money for the
specifications. It's also much harder doing the first open source
implementation, as there are no working references to, er, study.
So there's no immediate prospect of it being implemented by ReportLab

As always, if someone wants this badly and is willing to implement it,
we would happily work with them and include the feature; and if an
organisation needs it for a project, we could quote for that work.
