Thanks for your responses. I think I would go for option#1 as a short
term solution and option#3 for long term as I want my changes to be
finally included in Wireshark. I have another query regarding option#1.
When I send customers a custom Wireshark Installer, do I also need to
have a version numbering different from official Wireshark builds? Is
there somewhere I have to let customers/people know that is our
"private" build as opposed to what has been offcially released by
Wireshark (like in the About box or something)?

Thanks for your help in advance.

Don't expect a lot of support on getting them to work.  I'd probably

Why not go for #1 AND #3? 

Make a bug report with your dissector(s) and while waiting for
review/commit distribute a

Custom version.
