Mike,
I think you maybe mistaken in your assessment of the amount of women that can use computers in the over 35 age group. If you visit the internet cafe's the next time you visit China, you will see many middle aged ladies useing computers. They learn to use them, to keep in touch with their children that are studying at Universities in other cities, or other family members that are in different provinces etc, etc!!
The fact remains, that in a relationship that they want to be in, does require them to have just that little more determination and willingness to do whatever is neccessary to overcome the terrible drawbacks of trying to progress that relationship over the internet. If that means learning about how to use a computer, (and it only requires a short beginners course)
Then quite frankly i don't think that's too much to ask. The end result, is what they are here for, ...to find a husband that is suitable for them!!!!
