This tool aims at enabling seemless navigation between
PHP/MySQL, Zope.Plone, Java JSF & ASP.NET
  based sites.
This should use asymetric cryptography and
1-time-usage redirection URLs. (which means
repeat-based
 attack shall be futile)
SASL / LDAP interface is much appreciated. 

Programmatic interface:

For each targe language, provide the following:
- one function to generate a /magic/ URL from:
 A/ login
 B/ password
 C/ connection counter (to provide 1-time use URLs)
 D/ Public key for the site considered
 E/ "Base"-URL of this site
 F/ Position in this site (the page we actually want
to go to)
 G/ Dictionnary of {key, values} for optional data.
 H/ template of connection details (typically,
something like "connect.php?id=$K&url=$U")
- one reception page (the target of the /magic/ URL
above) that includes in a set of hooks triggered when:
 + auth is ok
 + auth is not ok (with a clear diagnostic of WHY it
is not ok)
 This reception page shall do the counter increment by
itself.
 The reception page shall be able to maintain a set of
different couples of { private_key, usage_counter }
 
Utilities:
- Generator for Private/Public key-pair; (if utility
is written in java: best)
 
Deliverables:
 - Java code + doc/javadocs (Sun JDK code - style)
 - PHP code + "doxygen" docs
 - Plone python example with doc. ZPT based!
 - Clear technical definition of the cryptographic
systems used. Ideally a LyX/Texmacs document should be
OK;
 - /All/ javadocs/doxygens/pydoc filled
 - MySQL DB
 - Ant based build scripts for the java part
 - Java part is JSF/Hibernate based.
 - AspectJ / Java5 OK
 - PHP5 OK for PHP part (ideally I would appreciate
PHP code which is compatible with PHP4 & PHP5)
 - Python 2.4 OK for the Plone part
 - ASP.NET part shall run and compile with
Mono/Linux/MySQL
 - Must include JUnit tests / PHPUnit etc.
 - A "demo" kit (micro example with hello-world kind
of PHP / Zope.Plone / JSF sites providing seamless
integration with LDAP or SASL)
  much appreciated.
 
Notes: you are encouraged to use BSD-license style
open cryptographic libraries such as openssl or
similar for java.
 (legion of bouncy castle for instance)  
 
 I would like prices divided in 3 sections:
 
 - Java / PHP
 - option for ASP.NET
 - option for Zope
