It's certainly not impossible.
You'll need to do a bit of maths for that though... or alternately just make a 1x2 hexagon shape, repeat it a lot in a few rows, crop the image until it tiles, then resize down.
I remember creating a tileable hexagon pattern in 32x32. It wasn't mathematically perfect but good enough to fool the eye. Do you absolutely need it mathematically perfect?
KDR can you post it? I think a non mathmatical version is the only one tht will work. I would like to see how you tweaked it (and if possible ask permission to use it as a basis for mine).
All I have is this: It dimensionally will never become a 1X2 enlarging or shrinking with repetition under 512 limitation.
Its the above picture. I can shrink or enlage that, and then repeat in order to make the pattern. The problem is the dimensional fraction never allows enough to gain a 1:1 or 1:2 ratio mathmatically.
Thats pretty damn good! Its still stretched. I think that mathmatically having a perfect tileable hexagon in the dimensional aspects we are limited to is impossible.
you could counter the squising with texture matrices
assuming you do something like large scale applying to surfaces it's relatively easy to modify texture coords of brushes and such, then you could scale the texture back to perfect proportions

Trial and error ... or a bit of mathematics
Hmm its funny all the online ones either use wacky dimensions or call a 8 sided one a hexagon (hmm and I thought I didnt know my terminology)
All I have is this:
A repeatable pattern is 128X75 (for 1 hexagon)

For what is this? I think I'm missing something. Do the sides have to be equal length as well?
If you squish it a little, I think vertically about 85%, you can tile 2x2.
