We are launching a big international web site, that has local web sites on other domains.

We are planning to configure the web site to behave in the following manner:

Of a user with German (de) accept-language header visits "mysite.com", he is automatically redirected to "mysite.de".

If on "mysite.de" he selects to go to "mysite.com", the specific "no redirect in future" cookie is added. Now, when he visits mysite.com, he is no longer redirected.

Will this "initial redirect" behavior have any negative implication of website's reputation in search engines?

Googlebot does not use or store cookies so you have no problem there. However, if the sites have similar content written in different languages you should use the rel=alternate and hreflang values as described in the following article:
