Is it possible to braze water bottle fittings etc to an older chrome-moly frame? How hard to do this?
Much easier to get something like the Zefal Gizmo. Plastic straps that wrap around frame and hold a nut to screw bottle cage onto. Attached is a close up of one in use on my Falcon.

Yes, it's possible and it's not at all difficult for a frame builder to add any fittings you desire. What it will require is a repaint afterward.
Years ago I had downtube shifter bosses added to an older Bridgestone Cr-Mo frame but I was having it repainted anyway.
You can also use Riv-Nuts.

+1 to Riv-Nuts. I used 4 of them on my sister's bike (it didn't have bottle cage braze ons) with no apparent problems after a year of riding. I did install them with a dab of JB Weld to ensure that they wouldn't spin on me.

Rivnuts are threaded rivets. Installed with a special tool or a wheel skewer. Requires drilling a holes in your frame.

So do the brazeons so that's a wash.
Unless the frame is being stripped and repainted or powder coated after brazing on the extra parts the rivet nut option is far better.
