Specifically, what is going on here...?
RewriteRule ^([_0-9a-zA-Z-]+)/([0-9]{4})/?([0-9]{1,2})?/?([0-9]{1,2})?/?([_0-9a-zA-Z-]+)?/?([0-9]+)?/?$ /wp-inst/index.php?wpblog=$1&year=$2&monthnum=$3&day=$4&name=$5&page=$6 [L]
Is the ([_0-9a-zA-Z-]+) part the domain name of the blog or just the name of the blog?
to get the thing u ask try to replace your rule with
RewriteRule ^([_0-9a-zA-Z-]+)/([0-9]{4})/?([0-9]{1,2})?/?([0-9]{1,2})?/?([_0-9a-zA-Z-]+)?/?([0-9]+)?/?$ /wp-inst/test.php?wpblog=$1&year=$2&monthnum=$3&day=$4&name=$5&page=$6 [L]
then create test.php and there add:
<?
print_r($_GET);
?>
and then u will understand :)

Use this applet to check the regular expression.
In English:
"^" means - from the beginning of the request URL (no host),
"([_0-9a-zA-Z-]+)" means - look for an _, a number, a letter or a - (if any),
if there is a match, then put that in variable 1
"/" means - after that look for a /,
"([0-9]{4})" means - then look for a four digit number and put that in variable 2
"/?" means - then there may be a /
"([0-9]{1,2})?" means - now look for 1 to 2 digit number (optional) and put that in variable 3
"([0-9]{1,2})?" means - now look for another 1 to 2 digit number (optional) and put that in variable 4
"([_0-9a-zA-Z-]+)?" means - look for some (optional) number/letters/-/_ and put that in variable 5
"([_0-9a-zA-Z-]+)?" means - look for some (optional) numbers and put that in variable 6
The rest says to use variables 1-6 to create the url that will be used to access your wordpress site.
