On a site with multiple networks (subdomains), I install Captcha under sites/all/modules, go into the admin interface through the primary domain (www.{mysite}.com), and there I can add it to various forms (in particular, comment_form). However, the Captcha field only shows up in the comment form on the primary domain, not on any of the subdomains. When I go to the Captcha admin page through any subdomain, it does not list any forms to add it to. There does not seem to be a way to enable Captcha for subdomains nor add it to the forms on subdomains.

Can you describe your setup in more detail? Your sites on the subdomains are separate sites with a separate settings.php (but running on the same codebase)? Are you sharing databases or tables?
I'm also using a mulitsite setup (same codebase, separate settings.php, separate databases), but don't experience the problem you are mentioning.

My 6 sites (one main and 5 subdomains) are running on the same codebase, same database, same tables, but different settings.php files. (The virtual host server alias is *.mysite.com, so everything goes through that.) Here is what I do to reproduce the issue: I enable the Captcha and ReCaptcha modules. Then I go to www.mysite.com/admin/user/captcha . There I can see the list of forms for the site. I click the dropdown next to "comment_form" and select "ReCaptcha". Then I go to subdomain.mysite.com/admin/user/captcha and I do not see any list of forms that I can select the challenge type, so there is no way for me to put Captcha on the comment form for the subdomain. I already tried checking "Add CAPTCHA adminstration links to forms" and it still doesn't show up on the subdomain.mysite.com page. What do you think is going on?

the following issue should enlighten you
#311538: CAPTCHA, subdomains and cookie domains
Short version: CAPTCHA requires sessions and cookies. If you work with subdomains, you should make sure your cookie domains are properly set.
