Can't say I have. Here's the modlist I'm using at the moment:
+Industrialization -- Can't play on a server without it unless I want a whole pile of work deleted every time I log on. Also, super useful both for improved involvement and utility lategame, as well as a resource sink.
+Balanced Wood to Coal (a bit overpowered, I think, but I couldn't find a more balanced one, and I'unno how to edit the ratio [or the coal spawnrate] myself now that pretty much all the game files are packed--which, incidentally, pissed me off) -- won't matter one way or another on my end, as it only affects a refining process.
+Silver's fuelmod -- Fixes the fuel rods from 50% the fuel of their components to 125%, making it worth refining fuel ore now. Also makes molten cores (from the UFO) fuel. Same as wood-to-coal re: compatibility. Don't use this. Finally got a chance to test it, and it looks like the... guy (I'll be charitable) managed to fuck up something this simple.
+Dyeing Bucket -- Pretty nifty mod that is mostly compatible with other mods and vanilla MP; lets you mix many more dyes and dye damned near everything you can wear or swing; something you've dyed in SP will still be the new color in a server without the mod.
+Stimlab -- Adds R&D stim-crafting process that uses all farmable plants, allows you to discover recipes and make stims with a multitude of different effects. Haven't tested it much, but it looks fairly balanced and seems to be a nice way to sink resources into something useful in the lategame.
+Furniture Recycling -- I think I mentioned it here earlier, lets you break down furniture you've looted for the same pixel price that you'd pay to print it. All it adds is a single station which is simple enough to replace. It's a nice way to help pay for all that expensive research, but more importantly it gives you a reason other than kleptomania to steal everything that isn't nailed down.
+Whatever the name of the current freebuild ship mod is: Duh. Build a kickass ship out of blocks, take it into vanilla MP no problem.
Red: Incompatible with vanilla, will delete items from the client's ship and inventory upon joining.
Orange: Technically incompatible with vanilla, but lost items are minor and trivial to replace.
Green: Vanilla-compatible.
Blue: Technically incompatible, but only difference is that certain processes have different levels of output in SP and vanilla MP.
