Interesting. What about providing an "againframe" environment (on par
with "appendix", "note", etc.)?

It would use "BEAMER_act" property to set the overlay specification, and
a "BEAMER_ref" property using link syntax to refer to a particular
section. Here's an example:

--8<---------------cut here---------------start------------->8---
* section
** My frame title                     :B_frame:
:PROPERTIES:
:BEAMER_env: frame
:END:

Some text. Some text.  Some text. Some text.
Some text. Some text.  Some text. Some text.

** section                                         :B_againframe:
  :PROPERTIES:
  :BEAMER_env: againframe
  :BEAMER_act: 2
  :BEAMER_ref: *My frame title
  :END:

  This section will create "\againframe<2>{sec-1-2}".

** Following frame
etc.
--8<---------------cut here---------------end--------------->8---

This is not really cleaner than your workaround, but at least, it feels
more integrated. Another advantage is that you don't need to know the
label of the frame being resumed.

For convenience, when asking for an "againframe",
`org-e-beamer-select-environment' would always ask for "act" and "ref"
properties, since those are mandatory anyway.

I don't mind implementing this, but I'm not sure it's worth the
(although limited) hassle.
