[NTLUG:Discuss] to 'sell' or not to sell opensource

[Richard Geoffrion]

I have found that many customers and potential customers do NOT like the
concept of FREE software.  They can not get over the concept of having a
company take responsibility for software used in their production
environments.

To this end I have decided to start charging for open source software I use
for my customers.  The money raised during the "sale" of open source
software can then be used to donate to the open source projects in question.
While I realize that I can't SELL open source product, I can charge for a CD
that represents the time and effort to download and then prepare the
customized compiled version of that software for their system.

I'm hoping to start making regular contributions to Samba, Dan(qmail , the
inter7 group, Sam V.(courier mta), apache, and whoever else I can find that
have 'donate' options.

So the question becomes..

How do I sell 'unsellable' software without selling it??

Mandatory donations? (an oxymoron)
Hide it in the hardware price and risk it being construed as an attempted
'sell' of open source?
Separate it into an additional labor line item? (what I fear I'll have to do
and would like to avoid)

How do YOU handle this on your invoices? What is your wording?
