Single-Fixed Touring Frame questions

I am planning on building up a touring frame for single-speed/fixed gear and I seem to have two options, each with their own problems. Any input from you knowledgable folks in the touring and in the fixed gear forums would be welcome.

The decision is between 135mm and 130mm rear dropouts.
-If I use a frame with the touring standard 135mm rear dropout spacing, I could get a Phil Wood Kiss Off rear hub, which would be awesome. In order to get a straight chainline (the Kiss Off having a 52mm chainline) I think I would need to use the outer ring of an MTB triple crank. I haven't seen this done, but it seems like the chainwheel might be way too far out from the frame. Would this get in the way of my leg? Affect my riding? Thoughts?
-If, on the other hand, I use a frame with 130mm spacing, I could use a Phil Wood track hub. The problem here is that the 130mm would mean a weaker wheel, and thus one less useful for loaded applications. It would also mean less spacing for big wheels and fenders. Also, if I wanted to do a serious touring trip and add a deraileur, I'd be stuck with a smaller cluster. No?

the surly crosscheck has 132.5mm dropouts, and it tours great, even fixed.

You can go with the wider spacing. I have a few single-speed frames with 135 mm spacing and I use a Paul WORD hub, a Phil KISS-OFF (both with a 52 mm chainline), and also a White ENO (with 47.5 mm chainline).

For the 52 mm chainline hubs, I use a standard Ultegra triple bottom bracket and an Ultegra double road crank with the chainring mounted in the outer position. Depending on your frame, you may or may not need to add a 1 mm spacer between the bottom bracket's right cup and the frame.

For the White hub, I use an Ultegra double bottom bracket and Ultegra road crank.

The chainline is nearly perfect in both cases, and the Q factor is no more than it would be with a standard triple. It's not an issue for me.

I used the road cranks and bottom brackets because I had them in my spare parts bin. If you've got MTB parts, they'll work as well.
