It's not a "problem" as such, just that getting them completely dry takes a while and I always thought was a PITA.
I happen to have also picked up an Osram Duka 50 safelight which lets me work with RA4 papers in an illumination level comparable to a dim black and white safelight. What I'll do when the bulb (no longer available at any price) burns out is another question, though I do have a Jobo LED one that's supposedly safe too and bounced off a white wall provides enough illumination to make out outlines, which is really all you need.
It's a myth that you can't use a safelight for color. P.E. has even said they routinely used one of the dark color printing safelights for RA4 at Kodak, recommendations to the contrary notwithstanding. That will be very dim, but even making out outlines is very helpful. I don't use the Duka for BW anymore, to save the bulb life for color.
Let me know how the Portra internegs work out. I'd but a slide duplicator in a heart beat if it's that easy but I'd prefer to be able to easily do larger format internegs of large format transparencies. Contact printing onto film sounds like a huge PITA to get exposure and maybe filtration right, though.
