Both in your question and answers, you have claimed things which are not true:
xepersian does not work with beamer (but bidi works!) and I don't want
to face with this type of issues when working with various package.
This clearly shows that you have little knowledge (if any) about the matter. It is neither
bidi fault that beamer does not work in RTL. It is an engine bug (
\special in RTL mode). Both
xepersian suffer because of the engine bug and the fact that you imagine
bidi works with beamer is that the direction outside frames is RTL when you use
bidi package. For the last part of your comment, again
bidi works with a lot of packages and there is not any need to do much really.
bidipresentation has lots of problems.
What problems are you talking about? It is not that I think it is free of any bugs but people are using it every day and they are so far happy with the results.
I don't think that developer of bidi(presentation) package can devote
its time to this problems
First you need to prove that indeed there are lots of problems (as you claimed) and then you need to prove that you have got in touch with me, told me about these problems but I did not answer your query because I said that I do not have time. That is a lie! I have never got any email from anyone like you described.
Now let's answer your questions.
