Please do not make a windows version or even remotely consider it. The people requesting it are a little short sighted and don't clearly understand the problem... Please don't ask them to screw it up.
I've been a Mac addict for 20 years, and as a professional using a computer for tasks beyond general consumer needs, I concur that there is definitely no parallel platform. However, since our software products were ported to Windows to maintain our position in the IT market, there are times when I am sadly forced into using a PC.
Many professionals use multi-platform setups and a real demand from the industry for a Windows compatible Teleport exists. IMHO, Synergy is not a solution.
It was the expansion of our freeware products for Mac to other platforms that enabled them to become, 12 years later, a global leader in their domain - at an extremely attractive price with tens of thousands of downloads from the general public, and B2B demands for API solutions from other world leaders in industry and commerce.
France - a very Mac-friendly country - is well known for being a cradle of simple, but innovative and popular IT solutions. I sincerely hope that Jule will one day be able to profit from such a move. The demand is market-technology driven.
