I find it that the franklang.ru site is yours, well done,it's a good job.
I couldn't find what you actually needed but I'm looking into it more.
here is a link to Pimsleur Language Program Farsi that has many listenings:http://dl2.irlanguage.com/Farsi/Pimsleu ... r.Farsi%20
it's not what you wanted but I should say what you are looking for should be a site for learning Persian for foreigners and usually the Persian books which Iranians use don't have any Latin/Cyrillic
so there are these sites for learners:http://www.easypersian.com/http://www.bbc.co.uk/languages/other/pe ... acts.shtml
but if there is any specific text that you want the translation or transliteration let me know,and I will do it for you.
about Rumi and others I should tell you that if there is any old literature or poem in persian it's modern persian not old. and every persian speaker is able to completely understand them. the old persian books were destroyed by Arabs and mongols invasions.
every persian speaker read these texts at school and the language they use is polite and formal, and you can find it in books and newspaper and formal meetings, but when we want to talk to friends and family and coworkers we use a Shekaste[broken] language which is informal.
the problem is if you as a foreigner learner, learn the informal form of persian you wouldn't understand the poems and literature but if you learn the formal you will be able to understand them both.because informal is like the street talk in american english. I assume every lang has this two different types of speech.
thanks for your interest.
